Northwest Rail Fans Eager for Sept. 30 Debut of Amtrak’s Airo Fleet
The 300-passenger Siemens-built trainsets will replace older cars on a mixed fleet schedule, but Washington and Oregon say travel times will not improve.
On Sept. 30, Amtrak will introduce the first two Airo Fleet trains to the Amtrak Cascades route, marking the start of a nationwide modernization effort spanning 83 trainsets.
Corrosion forced the removal of older Horizon cars from the Amtrak Cascades line in March 2025, reducing passenger capacity and prompting this fleet replacement to address long-standing service constraints.
The new Airo trains feature 300 seats, panoramic windows, and free Wi-Fi, while a $300 million federally-funded maintenance facility under construction south of downtown Seattle will support the modern railcars.
Two new trainsets will operate four daily trips initially between Seattle and Vancouver, and Seattle and Eugene, though current schedules will remain unchanged as Amtrak gradually replaces all existing Cascades trains through 2027.
WSDOT Secretary Julie Meredith called the launch a significant development for the Pacific Northwest as Amtrak prepares to introduce 83 Airo sets nationwide, with the Northeast Regional route next to receive the upgraded trains.
